ABSTRACT:
An electric motor has back-to-back zener diodes across each winding to short the reactance current over the threshold voltage upon polarity reversal, to serve the dual functions of reducing communtator arcing and increasing torque output by delaying the decay of the reactance current until the reversed current begins to surge after reversal. A resistor may be added in series with the series connected back-to-back zener diodes.
